Investment Objectives

The investment objective of the Palmer Square Ultra-Short Duration Investment GradeFund (the "Fund") is to seek income. A secondary objective of the Fund is to seek capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Shareholder Fees (fees paid directly from your investment)
Wire fee			$20
Overnight check delivery fee			$25
Retirement account fees (annual maintenance fee)			$15
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees			0.25%
Distribution (Rule 12b-1) fees			None
Other expenses			0.34%
Shareholder servicing fee	0.04%
All other expenses	0.30%
Total annual fund operating expenses			0.59%
Fees waived and/or expenses reimbursed1			(0.09)%
Total annual fund operating expenses after waiving fees and/or reimbursing expenses1			0.50%

1 The Fund's advisor has contractually agreed to waive its fees and/or pay for operating expenses of the Fund to ensure that total annual fund operating expenses (excluding any taxes, leverage interest, brokerage commissions, dividend and interest expenses on short sales, acquired fund fees and expenses (as determined in accordance with Form N-1A), expenses incurred in connection with any merger or reorganization, and extraordinary expenses such as litigation expenses) do not exceed 0.50% of the average daily net assets of the Fund. This agreement is in effect until October 31, 2025, and it may be terminated before that date only by the Trust's Board of Trustees. The Fund's advisor is permitted to seek reimbursement from the Fund, subject to certain limitations, of fees waived or payments made to the Fund for a period ending three full fiscal years after the date of the waiver or payment. This reimbursement may be requested from the Fund if the reimbursement will not cause the Fund's annual expense ratio to exceed the lesser of (a) the expense limitation in effect at the time such fees were waived or payments made, or (b) the expense limitation in effect at the time of the reimbursement.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The example reflects the Fund's contractual fee waiver and/or expense reimbursement only for the term of the contractual fee waiver and/or expense reimbursement.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

One Year	Three Years	Five Years	Ten Years
$51	$180	$320	$729

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 123% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities rated investment grade at time of purchase. Investment grade securities are those rated in the Baa3 or higher categories by Moody's Investors Service, Inc. ("Moody's"), or in the BBB- or higher categories by Standard & Poor's, a division of McGraw Hill Companies Inc. ("S&P"), or Fitch Ratings Ltd. ("Fitch") or, if unrated by Moody's, S&P, Fitch, or another Nationally Recognized Statistical Rating Organization ("NRSRO"), determined by Palmer Square Capital Management LLC (the "Advisor"), the Fund's advisor, to be of comparable credit quality. The types of debt securities in which the Fund may invest include, but are not limited to, (i) asset-backed securities, including collateralized loan obligations ("CLOs") and mortgage-backed securities, (ii) corporate bonds, notes, debentures and commercial paper, (iii) securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored entities, (iv) bank loans, (v) senior secured floating rate and fixed rate loans or debt, and (vi) second lien or other subordinated or unsecured floating rate and fixed rate loans or debt. The Fund may invest a significant portion of its assets in one or more investment types. The Fund's investment strategy involves active and frequent trading.

The Fund's asset-backed securities investments may be comprised of loans or leases secured by motor vehicles or other equipment, consumer receivables from sources such as credit cards or student loans, or cash flows from operating assets such as royalties and leases.

Mortgage-backed securities in which the Fund may invest include those issued or guaranteed by federal agencies and/or U.S. government sponsored instrumentalities, such as the Government National Mortgage Administration ("Ginnie Mae"), the Federal Housing Administration ("FHA"), the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac"). The Fund may also invest in commercial mortgage-backed securities ("CMBS") and collateralized mortgage-backed securities ("CMOs") issued or guaranteed by private entities.

The Fund's investments will generally be U.S. dollar denominated. While the Fund may invest in securities of any maturity, the Fund will maintain an average portfolio duration under normal market conditions of less than one year. Duration is a measure of the underlying portfolio's price sensitivity to changes in prevailing interest rates. The longer a security's duration, the more sensitive its price will be to changes in interest rates. For example, the price of a security with a one-year duration would be expected to decrease by approximately 1% in response to a 1% increase in interest rates. Calculations of duration may be based on estimates and may not reliably predict a security's sensitivity to changes in interest rates.

In pursuing the Fund's investment objectives, the Advisor uses a blend of top-down analysis, which includes macro analysis, analysis of valuation metrics across credit sectors, and sector monitoring, and bottom-up analysis, which involves individual issuer and management analysis and security/transaction evaluation that seeks to identify debt securities that it believes can provide highly competitive rate yields and total return over the long term with relatively mitigated credit risk.

As part of its overall investment process, the Fund's investments are subject to the Advisor's environmental, social and governance ("ESG") screening process, as described below. Generally, before the Fund invests in a corporate debt security, the Advisor analyzes the issuer's ESG risk profile using fundamental, bottom-up research as well as independent third-party data to assess whether an issuer should be considered for investment. The Advisor's ESG screening process is designed to largely exclude issuers that it believes are inconsistent with the goals and objectives expressed in the UN Global Compact's Principles and Sustainable Development Goals, which may change over time. In addition, the Advisor's ESG screening process seeks to exclude debt obligations of issuers that, together with any affiliates, are involved in and derive significant revenue (i.e., more than 50% of their revenue) from certain industries or product lines, including:

•the speculative extraction of oil and gas (commonly referred to as exploration and production);

•the speculative extraction of thermal coal or the generation of electricity using coal;

•hazardous chemicals, pesticides and wastes, or ozone depleting substances;

•endangered or protected wildlife or wildlife products, the production or trade of which is banned by applicable global conventions and agreements;

•pornography or prostitution;

•tobacco or tobacco-related products;

•subprime lending or payday lending activities;

•firearms or weapons, including controversial weapons (e.g., cluster bombs, anti-personnel mines, and chemical or biological weapons); and

•components or services that have been specifically designed or designated for military purposes, or for the functioning of controversial weapons.

Principal Risks of Investing

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objectives.

•Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geopolitical conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. In addition, local, regional or global events such as war, acts of terrorism, international conflicts, the spread of infectious illness or other public health issues, or other events could have a significant impact on a security or instrument. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market.

•InterestRate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the

more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund's income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund's investments. These risks are greater during periods of rising inflation. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

•Liquidity Risk. The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund's investments. Illiquid assets may also be difficult to value.

•Risk of Large Shareholder Redemptions. Certain entities, accounts, individuals may from time to time own (beneficially or of record) or control a significant percentage of the Fund's shares. Redemptions by these entities, accounts or individuals of their holdings in the Fund may impact the Fund's liquidity and net asset value per share ("NAV"). These redemptions may also force the Fund to sell securities, which may negatively impact the Fund's brokerage and tax costs.

•Valuation Risk. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued by the Advisor using a fair value methodology. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Advisor had not fair-valued the security or had used a different valuation methodology.

•Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer's credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

•Credit Risk. If an issuer or guarantor of a debt security held by the Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund's portfolio will typically decline.

•Extension Risk. If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

•Bank Loan Risk. The Fund's investments in secured and unsecured participations in bank loans and assignments of such loans may create substantial risk. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest, which will expose the Fund to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. Bank loan trades may also be subject to settlement delays. In addition, bank loans may not be considered securities under U.S. federal securities laws and, as a result, investments in them may not have the protection of federal securities laws.

•Senior Loan Risk. The Fund may invest in floating or adjustable rate senior loans. These investments are subject to increased credit and liquidity risks. Senior loan prices also may be adversely affected by supply-demand imbalances caused by conditions in the senior loan market or related markets. Below investment grade senior loans, like high-yield debt securities or junk bonds, usually are more credit than interest rate sensitive, although the value of these instruments may be affected by interest rate swings in the overall fixed income market. Senior

loans may be subject to structural subordination and, although the loans may be senior to equity and other debt securities in the borrower's capital structure, the loans may be subordinated to other obligations of the borrower or its subsidiaries.

•Collateralized Loan Obligations Risk. The Fund is subject to asset manager, legal and regulatory, limited recourse, liquidity, redemption, and reinvestment risks as a result of the structure of CLOs in which the Fund may invest. A CLO's performance is linked to the expertise of the CLO manager and its ability to manage the CLO portfolio. Changes in the regulation of CLOs may adversely affect the value of the CLO investments held by the Fund and the ability of the Fund to execute its investment strategy. CLO debt is payable solely from the proceeds of the CLO's underlying assets and, therefore, if the income from the underlying loans is insufficient to make payments on the CLO debt, no other assets will be available for payment. CLO debt securities may be subject to redemption and the timing of redemptions may adversely affect the returns on CLO debt. The CLO manager may not find suitable assets in which to invest and the CLO manager's opportunities to invest may be limited. As of June30, 2024, approximately 43% of the Fund's assets were invested in CLOs.

•Mortgage-Backed and Asset-Backed Securities Risk. Mortgage-backed and asset-backed securities represent interests in "pools" of mortgages or other assets, including consumer loans or receivables held in trust. Mortgage-backed securities are subject to "prepayment risk" (the risk that borrowers will repay a loan more quickly in periods of falling interest rates) and "extension risk" (the risk that borrowers will repay a loan more slowly in periods of rising interest rates). If the Fund invests in mortgage-backed or asset-backed securities that are subordinated to other interests in the same pool, the Fund may only receive payments after the pool's obligations to other investors have been satisfied. An unexpectedly high rate of defaults on the assets held by a pool may limit substantially the pool's ability to make payments of principal or interest to the Fund, reducing the values of those securities or in some cases rendering them worthless. The Fund's investments in other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as additional risks associated with the nature of the assets and the servicing of those assets. As of June30, 2024, approximately 17% of the Fund's assets were invested in mortgage-backed and asset-backed securities.

•Government-Sponsored Entities Risk. The Fund's investment in U.S. government obligations may include securities issued or guaranteed as to principal and interest by the U.S. government or its agencies or instrumentalities. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. As of June30, 2024, approximately 12% of the Fund's assets were invested in U.S. government securities.

•LIBOR Risk. The London Interbank Offered Rate ("LIBOR") was a leading benchmark or reference rate for various commercial and financial contracts, including corporate and municipal bonds, bank loans, asset-backed and mortgage-related securities, interest rate swaps and other derivatives. On July27, 2017, the United Kingdom's Financial Conduct Authority announced the gradual phase out of the LIBOR rate, with nearly all LIBOR rate publications having ceased as of June30, 2023 (some LIBOR rates continue to be published, but only on a temporary and synthetic basis). Alternatives to LIBOR have been established and others may be developed. The transition to a new reference rate may result in (i) increased volatility or illiquidity in markets for instruments or contracts that previously relied on or still rely on LIBOR; (ii) a reduction in the value of certain instruments or contracts held by the Fund; (iii) reduced effectiveness of related Fund transactions, such as hedging; (iv) additional tax, accounting and regulatory risks; or (v) costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to the Fund's investments resulting from a substitute reference rate may also adversely affect the Fund's performance and/or NAV.

•Private Placements and Restricted Securities Risk. Private placements and other restricted securities may be considered illiquid securities. Private placements typically are subject to restrictions on resale as a matter of contract or under federal securities laws. Because there may be relatively few potential purchasers for such

securities, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held. The absence of a liquid trading market may also make it difficult to determine the fair value of such securities for purposes of computing the Fund's net asset value.

•Subordinated Securities Risk. The Fund may invest in securities that are subordinated in right of payment to more senior securities of the issuer. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

•ESG Criteria Risk. While the Advisor believes that the integration of ESG analysis as part of the investment process contributes to its risk management approach, the Fund's consideration of ESG criteria in making its investment decisions may affect the Fund's exposure to risks associated with certain issuers, industries and sectors, which may impact the Fund's investment performance. In addition, because the Fund's ESG criteria exclude securities of certain issuers, the Fund may forgo some market opportunities available to funds that do not use these criteria. There are significant differences in the interpretation of what it means for an issuer to have positive ESG characteristics. While the Advisor believes its ESG criteria for excluding securities of certain issuers is reasonable, the Fund's investments may include securities of issuers that derive significant revenue from activities that are generally not within ESG guidelines.

•Management and Strategy Risk. The value of your investment depends on the judgment of the Advisor about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, which may prove to be incorrect.

•Portfolio Focus Risk. To the extent a significant portion of the Fund's assets is invested in one or more investment type, the Fund's exposure to the risks associated with that investment type or types will be greater than if the Fund's assets are diversified among many different investment types. As of June30, 2024, approximately 43% of the Fund's assets were invested in CLOs.

•Prepayment or Call Risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will not benefit from the rise in market price that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund may also lose any premium it paid on the security.

•Recent Market Events. Periods of market volatility may occur in response to market events and other economic, political, and global macro factors. For example, in recent years the COVID-19 pandemic, the large expansion of government deficits and debt as a result of government actions to mitigate the effects of the pandemic, Russia's invasion of Ukraine, and the rise of inflation have resulted in extreme volatility in the global economy and in global financial markets. These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund's investments, impair the Fund's ability to satisfy redemption requests, and negatively impact the Fund's performance.

•Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Advisor, and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder's ability to exchange or redeem Fund shares may be affected. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents.

•Portfolio Turnover Risk. Active and frequent trading of the Fund's portfolio securities may lead to higher transaction costs and may result in a greater number of taxable transactions than would otherwise be the case, which could negatively affect the Fund's performance. A high rate of portfolio turnover is 100% or more.
